NOTES

1 - The battery temperature detection is a function

of the characteristics of the NTC resistor used

inside the battery pack. Please consult factory.

2 - Different fast charge and trickle charge currents,

and different time out are available on request

(Maximum charge current cannot exceed 1A).

3 - For connector to the battery pack please consult

factory.
